Trixa . September, North Wales. The same species 



as that which Dr. Leach sent to Meigen, and which the latter 

 described as a variety of T. variegata, but observed that it i 

 might be distinct. 



Themira pilosa, Ent. Mag. Vol. I. p. 254. For Themira 

 pilosa, read Themira superba, Haliday, {Sepsis-idem, E. M. I. 

 170.) and transfer the reference to Themira putris. I am 

 indebted to Mr. Haliday for the correction of this error.
